"Sometimes I respond by saying something quite sarcastic and patronising, such as: 'Oh, it sounds like you need a hug?'

In 2015, Carland vowed to donate $1 to charity for every hate tweet she received. In just over two weeks, she had donated more than $1000.

The idea was to "respond to something awful with something good in a way that it doesn't really engage with what the trolls are doing", she said.

"I thought, what's a good thing I can do? What is the complete antithesis of what these people are doing? They are putting so much ugly into the world. I thought what something is good I can put into the world."

She has since donated a total of about $5200 to UNICEF but admitted it can be “hard to keep track of” all the mean tweets
